Analog Interface

VAREF

Input or

Output

Voltage reference – If using the internal voltage reference, this signal will be an output; if

using an external voltage reference, this signal will be an input for this reference (see the

FIXED_VAREFSEL and FIXED_VAREFSEL_VAL parameters/generics).

GNDREF

Input

Ground reference – If external voltage reference is used, this signal must be connected to the

ground for the reference; otherwise this should be connected to digital ground (logic 0).

AV9, AV8, AV7, AV6, AV5,

AV4, AV3, AV2, AV1, AV0

Input

Analog Voltage Monitor inputs – These signals correspond to the AVx voltage monitor inputs

(AV9 through AV0) of the AB macro.

Note: Unused AVx inputs need to be disabled with the CFG_AVx parameters/generics and

connected to logic 0.

AC9, AC8, AC7, AC6, AC5,

AC4, AC3, AC2, AC1, AC0

Input

Analog Current Monitor inputs – These signals correspond to the ACx current monitor

inputs (AC9 through AC0) of the AB macro.

Note: Unused ACx inputs need to be disabled with the CFG_ACx parameters/generics and

connected to logic 0.

AT9, AT8, AT7, AT6, AT5,

AT4, AT3, AT2, AT1, AT0

Input

Analog Temperature Monitor inputs – These signals correspond to the ATx temperature

monitor inputs (AT9 through AT0) of the AB macro.

Note: Unused ATx inputs need to be disabled with the CFG_ATx parameters/generics and

connected to logic 0.

ATRETURN4, ATRETURN3,

ATRETURN2, ATRETURN1,

ATRETURN0]

Input

Shared Analog Temperature Monitor Returns – These signals correspond to the shared

returns for the temperature monitor inputs (ATRETURN89 through ATRETURN01) of the AB

macro.

DAVOUT9, DAVOUT8,

DAVOUT7, DAVOUT6,

DAVOUT5, DAVOUT4,

DAVOUT3, DAVOUT2,

DAVOUT1, DAVOUT0

Output

Digital AV outputs – These signals correspond to the digital AV outputs (DAVOUT9 through

DAVOUT0) of the AB macro. If any of the AVx inputs are configured as digital inputs rather

than analog inputs, their corresponding buffered digital signals are put out on these ports.

DACOUT9, DACOUT8,

DACOUT7, DACOUT6,

DACOUT5, DACOUT4,

DACOUT3, DACOUT2,

DACOUT1, DACOUT0

Output

Digital AC outputs – These signals correspond to the digital AC outputs (DACOUT9 through

DACOUT0) of the AB macro. If any of the ACx inputs are configured as digital inputs rather

than analog inputs, their corresponding buffered digital signals are put out on these ports.

DATOUT9, DATOUT8,

DATOUT7, DATOUT6,

DATOUT5, DATOUT4,

DATOUT3, DATOUT2,

DATOUT1, DATOUT0

Output

Digital AT outputs – These signals correspond to the digital AT outputs (DATOUT9 through

DATOUT0) of the AB macro. If any of the ATx inputs are configured as digital inputs rather

than analog inputs, their corresponding buffered digital signals are put out on these ports.

DDGDON9, DDGDON8,

DDGDON7, DDGDON6,

DDGDON5, DDGDON4,

DDGDON3, DDGDON2,

DDGDON1, DDGDON0

Input

Direct Digital Gate Driver enables – These signals can control the corresponding GDONx

gate-driver enable inputs (GDON9 through GDON0) of the AB macro if the CFG_GDx

parameters/generics are set appropriately (refer to "Parameter/Generic Descriptions" on

page 6).

AG9, AG8, AG7 AG6, AG5,

AG4, AG3, AG2, AG1, AG0

Output

Analog Gate Driver outputs – These signals correspond to the AGx gate driver outputs (AG9

through AG0) of the AB macro.

Note: If unused, each of these gate driver outputs can be disabled via the CFG_GDx

parameters/generics.
